Title: Fuel injection device
Inventor: TERASAWA MICHITAKA
IPC: F02M47/02
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To quickly release the residual pressure of a pressure accumulating means by repeating a switching operation for the solenoid valve of an injector at a cycle shorter than a period for injecting fuel. SOLUTION: A feed pump 18 driven by engine power sucks fuel stored in a tank 15 and supplies fuel into the pressure room 13 of a pressure pump 10. The fuel in the pressure room 13 is pressurized by a plunger 11 and supplied to a common rail 23 and then the fuel is pressure-accumulated. The pressure of the common rail 23 is applied to an injector 26, electricity is conducted to a solenoid valve 59 to be excited and then fuel injection is carried out. In this fuel injection device, when a key switch is changed to be OFF, the solenoid coil 61 of the injector 26 is turned ON/OFF bit by bit by an electronic controller 30 at a short cycle and a time interval where fuel injection is not performed. Thus, back leakage is performed by the injector 26 and a pressure is reduced in the common rail 23.

IPC: D01B7/04
Filed: 1979-11-12
Abstract: PURPOSE: Water drops splashed from the yarn that is being reeled are collected, sericine and cotaminations are removed from the water and the resultant clean water is fed between the shaft of the revolving type yarn collector and the rotor, thus preventing the adhesion of sericine or other contaminations to the shaft to ensure the smooth rotation.

Further, the yarn 3 is passed through collector 4 and drum wheels 5, 6 and the yarns 3a and 3b form a kennel. When the yarn is passed through a coil guide 7 and taken up around a reel 8, the water drops on the surface of the yarn 3 are splashed when yarns 3a and 3b are twisted and simultaneously sericine and contaminations are scattered as well. A rotor composed of blade 9 and pulley 10 is loosely inserted into a shaft 2 and the shaft 2 is fixed to the mounting metal 13. A water tank 18 is fitted to the plate 12 so that the cut for water feed 16 is opposed to the water outlet 15. Splashed water drops containing sericine and other contaminations is introduced into the water tank 18 when sericine and others are removed by precipitation and clean water is always sent to the rotor.

Title: Optical scanner
Inventor: TAKADA TSUNEHISA
IPC: H04N1/113
Filed: 1993-06-17
Abstract: PURPOSE:To provide an optical scanner capable of correcting deformation caused by the dynamic distortion of the reflecting surface of a mirror rotation type light deflector and realizing high-accurate recording or reading. CONSTITUTION:A laser beam L outputted from a laser diode 14 is guided to a concave cylindrical lens 18 through a collimator lens 16 and diffused in a main-scanning direction (direction shown by an arrow X). Thereafter, it is reflected and deflected on the reflecting surface 24 of a rotary scanning mirror 20 formed to be concave in a major axis direction. Besides, it is guided to a film F through a scanning lens 22. In such a case, the reflecting surface 24 becomes plane in the major axis direction by centrifugal force generated by rotation. Besides, the concave deformation in a minor axis direction caused in accordance with the dynamic distortion of the reflecting surface 24 in the major axis direction is canceled by the lens 18. As a result, the beam L is guided to the film F without receiving the effect of the dynamic distortion of the reflecting surface 24. Thus, an image is accurately recorded.

CONSTITUTION:In an image processing apparatus for adjusting a business sheet 5 to the copied image according to the driving timing of an adjusting roll 3, the thickness of the business sheet is detected by a business-sheet thickness detecting means 8.

Title: Variable system for cooling and heating capability
Inventor: SUGIYAMA AKIRA
IPC: F24F5/00
Filed: 1981-09-16
Abstract: PURPOSE:To reduce noise with a simple construction, by a method wherein cooling or heating capability can be varied by changing over the inflow and outflow directions of a refrigerant or hot water passed through a heat exchanger, in a cooler-heating such that a cool air flow or a warm air flow is obtained by a refrigerant or hot water passed through a heat exchanger. CONSTITUTION:Hot water flows from a heat source 11 into an inlet 13 of the heat exchanger 12 through a four-way valve 15 as indicated by solid-line arrows, returns to the heat source through an outlet 14 and the valve 15, while releasing heat at the heat exchanger 12. Then, the valve 15 is changed over to cause the hot water to flow in the opposite direction as indicated by dotted-line arrows. Since the heat-exchanging effiency is largely changed by reversing the flowing direction of the hot air passed through the heat exchanger 12, the heat-exchanging capability can be changed while maintaining the rotating speed of a blower 16 to be constant. A similar effect is achieved also in a cooling operation. Accordingly, the harsh change of noise at the time of changing the rotating speed of the blower can be eliminated, and noise can be reduced.

Title: Method for measuring oxygen amount in molten material
Inventor: YAMAMOTO TOSHIYUKI
IPC: G01N27/411
Filed: 1990-06-05
Abstract: PURPOSE:To measure the amount of oxygen almost continuously by repeatedly alternating measuring operation by an oxygen concentration battery circuit and operation for applying the oxygen concentration battery circuit with a voltage in the opposite direction from the direction of an electromotive force generated at the time of the measurement. CONSTITUTION:A switch 13 is placed in a measurement state and an oxygen sensor is dipped in the molten material 1' to measure the electromotive force E. Before the measured value of the electromotive force E shifts toward 0mV, the switch 13 is switched to interrupt the oxygen amount measurement, and at the same time the oxygen concentration battery circuit is connected to an additional voltage circuit (battery 12). Consequently, when the oxygen concentration battery circuit is applied with the voltage in the opposite direction from the direction of the electromotive force E generated by the oxygen concentration battery, oxygen ions flow from the material 1' to a standard electrode material 4. Then a material 4 which is reduced during the oxygen amount measurement is oxidized and the oxygen partial pressure in the material 4 returns to its normal state. The measurement state and additional voltage state are alternated repeatedly to continuously and accurately measure the amount of oxygen in the material 1'. In this case, a constant-time dead state is provided in the transition from the additional voltage state to the measurement state.

Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a ball bearing device which can lessen the deflection of nonsynchronous revolution speed component of a spindle motor by restraining the transmission of vibration to a member for fixing a ball bearing. SOLUTION: An outer ring 6 is fixed to a hub 4 being an outer ring fixing member, and an inner ring 7 is fixed to a shaft member 3 being an inner ring fixing member, and a section which is the same in an axial position as the outer ring track 11 of the outer diametral face of the outer ring 6 is composed so as to come into contact with fluid.

Filed: 1990-06-07
Abstract: PURPOSE:To decrease the number of external terminals and to easily and freely change each mode by decoding a mode setting signal and outputting the data obtained through the decoding of the mode setting signal as the mode setting data. CONSTITUTION:A vertical synchronizing signal Vsync and a horizontal synchronizing signal Hsync are inputted to a decoder together with a data setting signal A. The decoder decodes the signal A based on both signals Hsync and Vsync. That is, the data C1 - Cn outputted from a latch group 14 are inputted to a control circuit as the mode setting data. Thus (n) modes are set by the control circuit, i.e., an NTSC system is applied if the data C1 is set at an H level as An with a PAL system applied with an L level of the data C1 respectively. As a result, the number of external terminals of a liquid crystal module is decreased and the signal A is changed. Then each mode can be freely and easily changed.
